3-5 Piping
1) Connect piping tightly so that no leak is found.
2) Use the pipe larger than 8 mm internal diameter for inlet / exhaust port piping.
3) In case the back pressure is inevitable, make it less than 0.03MPa.
4) Piping for evacuation of the container shall have a blocking valve as shown on Fig. 3-1 in order to
maintain vacuum status between an inlet pipe and container of the pump.
5)
In case of selecting the inlet pipe and exhaust pipe that are not from our products, please select the
exhaust pipe that has same or larger inner diameter length with the inlet pipe.
6) When connecting a pipe to inlet / exhaust port, always hold the inlet / exhaust port by hands.
Also, hold the inlet / exhaust port by hands when detach the pipe.
